A security-policy viewing procedure for AgentKeeper, a tool that checks coding-agent activity for risky behavior. It reports whether detection is local or connected and lists blocked tools, commands, paths, and threat patterns.

Reviewing AgentKeeper’s security mode, restrictions, and checks for threats such as credential theft, destructive deletion, reverse shells, and prompt injection.

It shows which safety checks are active before you rely on the tool to block dangerous actions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00050	$0.01168
Opus 5.5	$0.00020	$0.00467
Sonnet 5.5	$0.00010	$0.00234
Haiku 4.5	$0.00005	$0.00117

Security

Grade B, and why

policies scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Recursive force deletemediumDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

- recursive_delete_root — rm -rf / and system directory wipes

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

AgentKeeper Policies

You are displaying the organization's AgentKeeper security policies.

Step 1: Check Connection Mode

AGENTKEEPER_DIR="$HOME/.agentkeeper-plugin"
[ -n "$CLAUDE_PLUGIN_DATA" ] && AGENTKEEPER_DIR="$CLAUDE_PLUGIN_DATA"
cat "$AGENTKEEPER_DIR/api_key" 2>/dev/null

If no API key (local mode):

AgentKeeper Policies

Mode: Local (no account connected)

Running with default detection patterns. In local mode, AgentKeeper uses
a bundled set of 12 critical/high threat patterns:

  - credential_exfil — SSH keys, AWS creds, env files sent to network
  - reverse_shell — bash/python/nc reverse shell patterns
  - recursive_delete_root — rm -rf / and system directory wipes
  - dns_exfil — data exfiltration via DNS
  - system_file_write — writing to /etc, /usr, /System
  - ssh_config_write — modifying authorized_keys, SSH config
  - cryptominer — cryptocurrency mining patterns
  - startup_injection — modifying .bashrc, .zshrc, LaunchAgents
  - cicd_tampering — modifying GitHub Actions, GitLab CI
  - suid_manipulation — setting SUID bits
  - prompt_injection — common injection patterns in prompts
  - token_theft — stealing auth tokens and session data

Default behavior: warn (detect and flag, but allow execution)

To view and manage organization policies, connect an account:
  /agentkeeper:connect

Pro plan adds:
  - Custom blocked tool lists
  - Custom blocked command patterns
  - Path restriction policies
  - Custom blocklists (words, domains, patterns)
  - Policy enforcement across all team workstations

Stop here if local mode.

If API key exists (connected mode):

Proceed to Step 2.

Step 2: Fetch Policies

Fetch shield policy

AGENTKEEPER_DIR="$HOME/.agentkeeper-plugin"
[ -n "$CLAUDE_PLUGIN_DATA" ] && AGENTKEEPER_DIR="$CLAUDE_PLUGIN_DATA"
API_KEY=$(cat "$AGENTKEEPER_DIR/api_key")
curl -s --max-time 5 "https://www.agentkeeper.dev/api/v1/claude-code/policies" \
  -H "Authorization: Bearer $API_KEY"

If the endpoint returns an error or is not found, try the shield policies endpoint:

AGENTKEEPER_DIR="$HOME/.agentkeeper-plugin"
[ -n "$CLAUDE_PLUGIN_DATA" ] && AGENTKEEPER_DIR="$CLAUDE_PLUGIN_DATA"
API_KEY=$(cat "$AGENTKEEPER_DIR/api_key")
curl -s --max-time 5 "https://www.agentkeeper.dev/api/v1/shield/policies" \
  -H "Authorization: Bearer $API_KEY"

policies is a skill published in the GitHub repository rad-security/claude-code-plugin (3 stars, last pushed 23d ago), licensed MIT. It adds 50 tokens to every session and 1,168 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 2 findings (recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
